{"product_id":"led-drivers-current-source-white-4","title":"20W LED Driver 350-500mA - White","description":"\u003ch5\u003eDescription\u003c\/h5\u003e\u003cp\u003eThe Power supplies DALI is a 20W LED constant current driver delivering 350-500mA output from a 100-260V AC mains input. The driver converts household voltage to a regulated DC current suitable for LED panels, downlights, and strip lighting that require a constant current supply rather than constant voltage. The white plastic housing measures approximately 190mm x 55mm x 40mm and features ribbed cooling fins on the upper surface to dissipate heat during operation.\u003c\/p\u003e\n\u003cp\u003eDesigned for residential and light commercial installations, the driver mounts inside ceiling voids, behind light panels, or within cabinets where IP20 dry-location protection is sufficient. The screw terminal connections at each end accept typical 0.5-1.5mm² lighting cable, and the input accepts the full international mains range from 100V to 260V, making it compatible with UK 230V supplies without requiring voltage selection or manual switching.\u003c\/p\u003e\n\u003cp\u003eThe driver is rated for continuous operation at full 20W load and includes short-circuit, overload, and over-temperature protection. The output current is factory-set within the 350-500mA range depending on the connected LED load, automatically adjusting to maintain constant current as the LED ages or as ambient temperature varies. The non-dimmable design means it should not be paired with wall dimmers or control systems expecting a dimming response.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e20 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP 20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage\u003c\/td\u003e\n\u003ctd\u003eAC 100-260 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Current\u003c\/td\u003e\n\u003ctd\u003e350-500 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimmable\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003ePlastic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eWhite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/PSL-DL40-S-350-500mA-DE_datasheet.pdf?v=1783054874\" target=\"_blank\" rel=\"noopener\"\u003eProduct manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\u003cp\u003e\u003cstrong\u003eWhat LED fittings is this driver suitable for?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis driver suits LED panels, downlights, and strip lighting that require a constant current supply of 350-500mA and draw up to 20W total load.
